What is the appropriate first-aid measure for a knocked-out permanent tooth?

  1. Scrub the tooth clean with soap and water
  2. Place the tooth in milk or saline solution
  3. Allow the tooth to dry out before replanting
  4. Wrap the tooth in gauze and store at room temperature
Show answer and explanation

Correct answer: Place the tooth in milk or saline solution

Storing the tooth in milk or saline helps preserve periodontal ligament cells. This increases the chance of successful reimplantation.
